There are two coexisting realities classified under New Testament eschatology: the temporal and spatial. While much scholarly attention has focused on the temporal, Luke Woo argues that the spatial aspect is either neglected or relegated to Platonic or cosmological categories. Woo thus seeks to provide a holistic understanding, by investigating these realities for believers under the heavenly tabernacle motif in the Epistle to the Hebrews.

Woo posits that the author of Hebrews presents the heavenly tabernacle and all its high priestly activity in order to eschatologically situate, orient, and ground believers; thus enabling believers to actualize their heavenly, priestly identity by serving as priests on earth. Woo uses Edward Soja's Tripartite Critical Spatiality to analyze the heavenly tabernacle’s Firstspace, Secondspace, and Thirdspace features found in Hebrews 4:14; 8:1–5; 9:1–14. He suggests that Christ, in his resurrection and ascension, enters an actualized, heavenly tabernacle, which allows believers to spiritually occupy that sanctuary space in the presence of God, establishing a spatial orientation for believers who can identify as heavenly priests and be motivated to serve as such as they live on earth.
